[3PS-04]【J】Gene Expression and Chromosomal Regulation Diversity across Model Organisms, and in Tissue- and Developmental Stage-Specific Contexts

Fri. Dec 5, 2025 2:20 PM - 4:20 PM JST
Fri. Dec 5, 2025 5:20 AM - 7:20 AM UTC
Room 4(Pacifico Yokohama Conference Center 3F, 303)
Organizer: Hiroki Shibuya (RIKEN), Takashi Fukaya (The University of Tokyo)
To understand the fundamental principles of life, simple case studies using specific model organisms or homogeneous cell populations are not sufficient. By analyzing a diverse range of model organisms, from animals to plants (and even non-model organisms), and making comparisons within the same model organism across different developmental stages and organ types, we can uncover species-, developmental stage-, and organ-specific regulatory mechanisms, or, conversely, regulatory processes that exhibit functional convergence or robust conservation. In this symposium, we will introduce various model studies from the perspectives of gene expression and chromosomal regulation, including comparisons between animals and plants, somatic and germ cells, and discuss future directions in biological research.
